Problems solved by technology

[0002] In the process of casting steel, a stopper rod is installed in the nozzle of the molten steel tundish to control the flow of molten steel in the nozzle of the tundish. In addition, a temperature measuring tube needs to be installed to detect the temperature of the molten steel. The stopper rod and the temperature measuring tube are consumables. Regular replacement is expensive

Abstract

A pouring box stopper used for continuous casting relates to an auxiliary fitting part comprising a stopper body, in which a corundum tube is mounted; and the upper end of the corundum tube is connected with a temperature measuring device, which comprises a water-cooling device or a wind-cooling device, a temperature measuring probe and a temperature measuring meter, wherein the temperature measuring probe is connected with the temperature measuring meter through a conducting wire. By adopting the above structure, the corundum tube is mounted in the stopper body, and the improved stopper has the temperature measuring function, thereby eliminating the need of installing an additional temperature measuring tube in the pouring box, reducing the manufacture cost of cast steel, reducing the labor intensity, and simplifying the operation flow; furthermore, since the stopper body directly faces to the corresponding molten steel outlet, the temperature of the molten steel inside a crystallizer can be effectively monitored, thereby providing more precise temperature parameters for the automatic control of the pulling rate.

Description

Technical field: [0001] The invention relates to an auxiliary fitting for steel casting, in particular to an improvement on the structure of a tundish stopper for continuous casting. Background technique: [0002] In the process of casting steel, a stopper rod is installed in the nozzle of the molten steel tundish to control the flow of molten steel in the nozzle of the tundish. In addition, a temperature measuring tube needs to be installed to detect the temperature of the molten steel. The stopper rod and the temperature measuring tube are consumables. Regular replacement is expensive. Invention content: [0003] In order to solve the above existing problems, the invention provides a tundish plug rod for continuous casting that reduces the cost of steel casting; A corundum tube is installed in the stopper rod body, and the upper end of the corundum tube is connected to a temperature measuring device. The temperature measuring device includes a water cooling or air cooli...
